Stainless fittings, valve, fuel tank install, 170

[MichaelO]

OK, given, I'm often guilty of quality overkill, but, that doesn't mean I want to change my habits.

For my fuel tank install, I need a 316 3/8" stainless barb to 1/4"NPT to mate with the aluminum fuel outlet fitting.  I do not want to use bronze or brass in contact with aluminum.

I also need a fuel shutoff valve.  My dream valve would look like this:

as far as having mounting feet.  If would have 1/4"NPT or 3/8" barb ports, and be 316 stainless.  I'd prefer not to use bronze, as those valves always seem to have brass and steel as well.  I've reached down to shutoff a typical bronze valve before, only to discover the steel shaft has frozen.

And I have never felt that brass belonged anywhere on a saltwater boat, particularly on something well out of view and touched only every few years or in an emergency.

Anyone have any sources, or other approaches?

Thanks,

heres the pic. Thought I would help your cause in the only way I know how.

What I am looking for may not exist, and in the interest of expediency, I might just use what is there for now.  I'm wondering though, how was the fuel outlet originally routed?  Is mine original?

Here is the top of the fuel tank cover showing the block of wood and shutoff valve:
    

You can see the hose is routed through the fuel tank cover and siliconed in place; here is the bottom of the cover:



How are other 170s done?

And here are a couple of shots of the boat after initial cleanup (I apologize for poor image quality, I'm using my phone until I resolve my camera issues):
